Meet Truebit

Truebit gives developers a way to verify computations and automated actions that happen outside a blockchain. Its Truebit Verify platform runs custom code and API tasks, returning results alongside cryptographically signed transcripts of the inputs, outputs, and execution steps. Teams can use it to connect smart contracts with external data, coordinate AI model calls, and document how automated decisions were made.

Developers build and test tasks with a command-line toolkit, invoke them through web services, or connect them into workflows using tools such as n8n. Function tasks run in isolated WebAssembly environments, while API tasks support access to private services. The resulting records help developers and auditors inspect offchain activity, including data transformations and interactions spanning multiple systems.
